CT pattern of progression (upper panel A‐D) in an 83‐year‐old female deceased patient with fever and shortness of breath for 3 days. A, Initial CT (3 days from onset) only shows interlobular septal thickening in both lobes. B, Follow‐up CT obtained 5 days later shows multiple bilateral ground‐glass opacities (GGOs). C, Subsequent follow‐up CT obtained after another 3 days shows bilateral progressive CT progression. D, Final CT obtained after another 16 days shows “white lung” in both lungs, and the patient died of respiratory failure after 2 days. CT pattern of progression (lower panel A‐D) in a 48‐year‐old male recovered patient who presented with fever and cough for 3 days. A, Initial CT (3 days from onset): multiple irregular GGOs distributed bilaterally are shown. B, On day 7, there was a diffuse enlargement of GGO with partial consolidation and increased density. C, Day 10, further deteriorated GGO, which reached a peak level, with consolidation and air bronchogram. D, On day 19, the obvious resolution of GGO with fibrous stripes was observed.
